IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 189,242, dated April 3,1877; application filed February 8,1877.

To all whom it may concern:

Be it known that I, FORDYGE A.-LYMAN, of Cleveland, county of Guyahoga,and State of Ohio, have invented certain new and use ful Improvements inVapor-Burners, of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, and tothe letters. of reference marked thereon.

Figure 1 is a partial section and elevationof the burner; Fig. 2, a planof the base of the burner, showing the perforations leading to theheating-drum; and Fig. 3 is a cross section on line a: :r of Fig. 1.

The objects of my invention are, mainly, to provide an effective meansof regulating the amount of gas intended to be consumed for the purposeof forming an auxiliary heatingflame; to provide a heating-drum whichshall effectually prevent the accumulation or deposit of soot upon theburner; to supply a chamber or chambers for a quantity of reserved gasor superheated oil; and to provide a valve-stem which shall be soconstructed as that it will not be damaged by the cooling of the burner,or by being pressed too strongly against its seat; to accomplish all ofwhich it (the invention) consists in certain novel combinations andarrangements of parts, all of which will first be fully described, andthen pointed out in the claims.

L is the ordinary stand-pipe of the burner, which rises from thesupply-pipe S, and serves to conduct the oil to the point where it isvaporized. This stand-pipe is surmounted by the burner-supporting arms 0O, which also serve to convey heat to the upper portion ofthesupply-pipe, usually denominated the vaporizing-chamber.

Heretofore these arms have been heated by jets of inflamed gas impingingthereon, or by convection of heat from/"the burner proper, and no meanshas been provided for regulatin g the size of this auxiliary gas-jet.For economy in the consumption of the liquid fuel, as well as the properand most efficient working of the burner, it is desirable that some suchmeans be employed, and for this purpose I have designed the followingmeans: I

I surmount the arms 0 O by a plate, I, upon which the auxiliary jet mustimpinge. This jet is conducted downwardly from the burnercap T, within ashort pipe or drum, W, surrounding the screw-threaded pipe B, whichcarries the mingled gas and air from the orifice R to said burner T.Upon the bottom of pipe or drum W is a horizontal flange, a, which maybe brought nearer to or farther from the plate I, as desired, by simplyrevolving the burner upon the screw-threaded pipe B, the burner and drumbeing connected, and the latter having within it the perforated andscrew-threaded flange c. From this construction it is apparent that theamount of gas which issues beneath the plate a will be dependent uponthe size of the opening between said plate and the plate I, and thatthis opening may be increased or diminished, as desired.

The economical consumption of fuel, and its most perfect combustion, isoften dependent upon the relative distance between the gasjet orificeand the mixing-chamber, and this I distance is "ariable. according tothe quality and quantity of oil being consumed. Ordi= narily it shouldbe'from three to three and onehalf inches. described it will be observedthat the burner '1 may be brought near to or'withdrawn from the orificeIt at pleasure; and in order that the adjustments of the burner T anddrum \V may be made with any required nicety or pre-. cision, said drumis connected to the bottom of the burner by means of a shortscrew-thread,

7c. permitting it to be lowered a little distance;

if necessary, without disturbing the position of the burner.

The drum W is, when the burner is in operation, filled with ahighly-heated flame, and such is the intensity thereof as to prevent theaccumulation or deposit of soot upon any portion of the burner. Thisfeature avoids the disagreeable odor which often arises in this class ofburners from the burning soot, and

adds greatly to the heating effects of the device.

Within the arms 0 O I provide chambers D D, which serve to contain areserve supply of heated oil or gas, deriving their supply, of course,from the oil-pipe L, into which theyopen. This reserve supply of oil orgas is very useful in cases where the burner is extin- From theconstruction already.

.sponding guished and relighted in a short time thereafter, and itrenders the necessary vaporization of the oil more uniform and more easyto be accomplished. The chambers present a supply of oil which is veryeasily heated by the initiatory flame from the oil-cup K in the operation of starting the burner.

The burner is, ordinarily, lighted by allowing a small quantity of oilto flow over into the cup K, which, upon being ignited, heats up thevaporizing-chamber and its surroundin g parts, and thus supplies theinitiatory vapor, which is afterward kept up by the heat from the burneror from the auxiliary heatingflame.

The inner flange 0 is located below the base of the mixing-chamber,thereby affording an auxiliary chamber, which collects and directs thegas intended to be employed in the drum W.-

It is desirable that the valve employed to regulate the flow of oil orgas be made to revolve in. its seat, in order to clear the same fromobstructions, which frequently occur, in the shape of dust and sediment.

Heretofore the needle valves, which are most commonly employed in thisclass of burners, have been made with solid shafts, and are, therefore,frequently forced strongly against their seats, to the constant wear andinjury of the latter. This style of valve is, moreover, liable to injuryby the contraction of the valve-chamber upon cooling after being highlyheated, causing a great strain on the valve-seat, or else the bending ofthe valveror To avoid this difficulty, and yet preserve the valuablefeatures of the needle-valve, I propose to construct the shaft in twosections and interpose a spring, by which construction I am enabledstill to revolve the valve, and thus keep the seat clear, to prevent thevalve being forced forward too strongly, and to provide for itsautomatic contraction to correspond with that of the valve-rod chamber.

111 the drawing, E is the section having the valve projection, and M theportion which is screw-threaded to cause its adjustment to or from thevalve-seat. The section B has a hollow angular socket, fitting looselyover a correprojection on the section M, and between the two sections isinterposed the spiral spring F, exerting its elastic influence upon thetwo parts through the medium of suitablyfastened plates or pins 12.

From this construction and arrangement it is obvious M through itshand-wheel Y will cause a simi' lar revolution of the valve, that if thevalve be pressed the section M will only cause its angular projection toslide within the section E, and bring into play the elastic force of thespring, and

which would therefore, state that that any revolution of the section toits seat further advancement of that no amount of contraction in thepipe L can operate to bend the valve-shaft.

The devices illustrated for the purpose of regulating the auxiliaryheatingflame and for preventing injury to the valverod are the simplestwhich I have been able to contrive. It is apparent that many ways may bedevised for producing the same or like results, all of fall within thespirit of my invention and meaning of my claims. I will,

I do not desire to be confined to the exact devices illustrated in thedrawing.

Having now fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- 1. Theheating pipe or drum W, serving to conduct gas from the mixing-chamberdownwardly, for the purpose of forming the auxiliary heating-flame, thesame being vertically adjustable independently of said burner ormixing-chamber, substantially in the manner and for the purposes setforth.

2. In a vapor-burner in which the supply of oil is fed to thevaporizing-chamber from a point below the same, the combination, withsaid vaporizing-chamber, of the hollow arms projecting upwardlytherefrom, for the purpose of supporting the burner, and adapted tocontain a reserve supply of oil, as and for the purposes explained.-

3. In a gasoline or vapor stove, the combination of the gas-jet orifice,forming the valve-seat, and shaft and interposed spring, for thepurposes explained.

4. In combination with the burner T, the depending and adjustable drum,having a horizontal flange at its lower end, operating in conjunctionwith the plate I, for the purpose of regulating the auxiliary flame,substantially as shown.

5. The perforated flange c, in combination with the screw-threaded pipeB and burner T, substantially as set forth.

6. The combination of the burner-supporting arms, provided with cap orplate I, the screw-threaded pipe B, and vertically-adjustable drum W,having the horizontal flange, as and for the purposes explained.

7. The valve-rod composed of the two sections E and M, and provided withplates or pins p, combined with the spring F, the'whole being arrangedand adapted to operate in the manner shown and described.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.
